Magna Carta and the Common Law
This is the answer to your question
Answer:
Necessary and Proper Clause
Explanation:
The Necessary and Proper Clause allows the Federal Government to make laws that are necessary for the exercise of other powers established by the Constitution.
"[The Congress shall have Power . . .] To make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof."
I believe the best option would be A because both compromises aimed to appease the growing friction between the north and south.
